I just renamed my main user (belongs to administrators), and now many metro apps including the Store-App won't open. The outer border appears but then they crash and disappear. A second user that I created afterwards doesn't have this problem. So something is broken in my main user account.
Those are the error logged in the event viewer:

and Error (Event-ID: 5973)
Activation of app Microsoft.WindowsStore_8wekyb3d8bbwe!App failed with error: The remote procedure call failed. See the Microsoft-Windows-TWinUI/Operational log for additional information.
Also, I have no idea where I could find this "Microsoft-Windows-TWinUI/Operational log", mentioned in the third error report. Anyone having any idea? I don't want to create a new user account and switch everything over.
EDIT: Hm, I wanted to give the suggested solutions a shot today. But apparently the problem went away? I have no explanation for this. I have never encountered a problem like this going away on its own in almost 20 years PC experience. I am sorry, I cannot try any of your solutions now to not break the system (again). Still, thank you everyone for your effort. It is well appreciated!
